Hi, may i know what's die-cast tuners ? Any advantages ? (or disadvantages)

Die-cast (machine) tuners are the individual parts formed from molten metal, injected into a precision machined die, and allowed to partially cool before being ejected from the molding mechanism. Once fully cooled, the parts are subjected to limited machining and polishing prior to being plated. Different materials are used, but the idea is to produce a very precise part at a lower cost (than fabricating or fully machining).

No distinct advantage or disadvantage, die-casting is just a manufacturing method for tuners.
